Commended by fellow road traveller
By Max Asst
Yesterday, a late model SUV was veering into my lane, almost into my front passenger corner. I tapped the horn and the sound certainly excited the driver. He quickly veered away and once he sorted himself out, he came to realize it was my Hella Horn. I looked into my rearview mirror as he expressed his admiration of the product by using the longest finger on his right hand held up high, as if saying, "It's Number One!". I reciprocated agreement with the same gesture of lifting my 3rd digit to him, too, and mouthed to him, "It's FUN, Dude!", with special emphasis on the FUN. I drove along my merry way, working around slower traffic but the moment I settled behind a vehicle, the white SUV driver came along screaming up my side again to express his enthusiasm once more with a, "It's Number One!" gensture, now with his left hand out the driver's window, to make sure I saw it. I responded by leaning forward towards the dash, as sometimes I think the tinted windows may ha ve obscured my initial response, and I mouthed over to him once more a hearty, "FUN, DUDE!" Oh yes, good times, good times. Excellent purchase.

Mess-in-your-pants LOUD!
By EtchyLives
Watch Video Here: http://www.amazon.com/review/R1A31CNOPOFXJW First off, these are loud. Very loud. I know there are some people out there that claim theses horns are not *that* loud, but when properly installed (more on that in a bit) these things will get the attention needed in all traffic situations. Allow me to explain why I bought these horns and why you should do it, too.

I live in Korea and drive quite a bit. I own a 1998 Hyundai AtoZ, which is essentially a lunchbox with wheels. It's old, it's a tin can, has no airbags, no power windows, no power locks, the radio doesn't work, blah blah blah you get the idea - it's a piece of junk. It also had a little tiny horn to match the car's overwhelmingly tiny stature. Boo. If you haven't driven in Korea then this review might be lost on you, but let me explain the driving conditions, here. Seoul is like San Francisco - packed with cars and people. The sp aces between Seoul and other larger cities are the wild-west when it comes to driving. The only laws that most people abide by are laws enforced by cameras (red light cameras and highway cameras) and the law of "might = right". Remember that I'm driving a 14 year old tin can with an 800cc engine that, when new, had 53 horsepower.

Enter the Hella Supertones. I have had to start using restraint with my horn-blowing. It literally startles people to the point that their car swerves. Before I bought the Supertones I would drive around wailing on the center of my steering column with reckless abandon - firing off tiny and tinny little tweets of rage and irritation. Now I have to carefully calculate the validity of using my horn. Does that little old lady driving a car similar to mine who happens to be ever so slightly crossing into my lane REALLY need a stroke right now? Or does she need a pillow on which to sit so she have better spatial awareness? These are the dilemm as I now face on a daily basis. With great power comes red spider pajamas, and in this case the red spider pajamas are in fact, BIG RED HORNS OF DEATH. However, in certain situations (about once a week) I get to unleash the full fury of the angry god Hella.

Recently some guy in a black Equus decided to merge into my lane - and by "into my lane" I mean "into the same geographic area that I was currently busy... existing". This is pretty standard fare, here. Guy in expensive black car gets to drive whenever and however he likes and people generally have the transport-equivalent experience of getting their lunch money taken by a bully. Except in my case. I am the gun-toting school kid that makes sure the bully will think twice before trying to steal ANYONE's lunch money ever again. I am also the reason that a certain black Equus nearly slammed into another big black car that was going to do the same thing when the original Equus swerved wildly to the left at the sou nding of my horns. I then engaged in horrifically childish (and hilarious) behavior when I rolled down the window and pointed and laughed. Big, sweeping gestures. Loud, raucous laughter. For two straight minutes at the next light. The other driver wouldn't even look up from his steering wheel.

So, yes: These horns are loud. They are the equalizer, here in Korea. Just make sure that you install them CORRECTLY. Use the included relay or buy the recommended relay on here. The relay recommended here on Amazon has an additional contact for the second horn (less splicing). Also, the wiring harness from here simplifies the whole soldering/crimping process quite a bit. Finally, DO NOT TRY TO INSTALL THESE WITH YOUR EXISTING HORNS. You will actually REDUCE the dB output. In the case of horns more does not equal better.

Sound even better than they look!
By Tyler F. Simmons
These horns are fantastic! I just put in a new touchscreen HU in the car and wanted a simple upgrade to the alarm system. These horns easily accomplished that. The other night at the grocery store I tested it by hitting the panic button and watching at least a handful of people look at my car versus just ignoring it like most people do to most cars. I have been incredibly tempted to beep at people all over the place but I have to remind myself that this horn is scary loud. So far I only had to beep at an old man who was coming over in my lane as I was passing him, needless to say he got back in his lane with the quickness.
